The injector comprises a tip having at least one outlet orifice (,) for fuel delivered to an engine combustion chamber. A ceramic coating (,) is deposited on the external face of the tip, preferably in a kink (,) bounding a recess in this external face, at least around and immediately downstream of the outlet orifice (,) relative to the direction in which the fuel is delivered. This invention is applicable to fuel injectors with a ceramic coating to protect against deposits of carbon oil for use with spark-ignition and direct injection internal combustion engines.
